I have situation where I have aqueous sugar solutions that may also contain low levels of protein and/or some lipids...

I have to clean out the other stuff besides the sugars before going on to the next step in the process and it needs to stay aqueous. I was thinking that I might be able to do that using a C18 SPE cartridge and eluting with just water. My thought is that the sugars would not retain but the other stuff would.

Is that likely to work?

Thanks,

Should be able to achieve it easily with dSPE - that'll let you just shake it, centrifuge it and keep going.

Karen,

The pores on the C18 might be too small to capture the proteins. Find something with a very large pore size.
